Further describe by reference to the accompanying drawings again teaching demonstration example of the present utility model below:
Demonstration example one: " knowledge counting number " teaching demonstration pattern
It is to carry out as follows the operation of " knowledge counting number " teaching demonstration: first ten beads 14 are stirred one by one and slid onto rear end rail section and make ten beads 14 all be positioned at the position of impulse stroke switch below 15 along guide rail 1, press power switch 10, controller 5 each modules are carried out after initialization, function switch 8 is moved to the left while making " knowledge counting number " gear that it is placed in left end, the shown initial value of light-emitting diode display 3 is zero again.It should be noted that: under the mode of operation of " knowledge counting number ", controller 5 can not receive the output signal of putting number plus-minus switch 12 and reset switch 4.So far, can carry out the teaching demonstration training and operation of " knowledge counting number ": ten beads 14 one by one being stirred in the rail section of rear end by teacher or the head of a family make it slide onto the front end rail section of guide rail 1, when bead 14 passes through the position of equipped impulse stroke switch 15 along guide rail 1 slippage, contact 17 conducting impulse stroke switch 15 that bead 14 can be touched impulse stroke switch 15 produce a pulse electrical signal, by signal conductor 16 by pulse electrical signal input pulse signal-count module, after single-chip microcomputer carries out computing, can on light-emitting diode display 3, demonstrate current slippage by the arabic numeral value of the bead number of impulse stroke switch 15 positions, that is to say, the shown numeral of light-emitting diode display 3 is along with the bead number by impulse stroke switch 15 positions increases progressively one by one, when first to the 9th bead slips over impulse stroke switch 15 position, on light-emitting diode display 3, can in turn show " 1 ", " 2 ", " 3 ", " 4 ", " 5 ", " 6 ", " 7 ", " 8 ", the arabic numeral of " 9 ", when the position of impulse stroke switch 15 is passed through in the tenth namely last bead slippage, light-emitting diode display 3 meeting automatic clears show the numeral of " 0 ".Finally, allow child by aforesaid operations mode, repeatedly practise voluntarily, can make child be at play in very soon association understanding " 1 ", " 2 ", " 3 ", " 4 ", " 5 ", " 6 ", " 7 ", " 8 ", " 9 " arabic numeral and can set up intuitively the relevance between abstract numeral and corresponding bead in kind, can strengthen fast the learning ability that child " knows number, counting ", to promoting child, the learning interest of arithmetic, raising school grade be had to obvious teaching efficiency.
Demonstration example two: " putting number " teaching demonstration pattern
It is to carry out as follows the operation of " putting number " teaching demonstration: ten beads 14 are stirred and slid onto rear end rail fragment position along guide rail 1, press after power switch 10 device 5 initialization to be controlled, function switch 8 is moved right while making " putting number " gear that it is placed in right-hand member, and the shown initial value of light-emitting diode display 3 is zero.It should be noted that: under the mode of operation of " putting number ", the output signal that controller 5 can received pulse travel switch 15, the shown digital value of light-emitting diode display 3 is the carrying out increasing or decreasing one by one of putting number plus-minus switch 12 two ends number of times along with pressing.So far, can carry out the teaching demonstration training and operation of " putting number ": first by teacher or the head of a family, press the two ends of putting number plus-minus switch 12, certain concrete digital value from " 1 " to " 9 " is set on light-emitting diode display 3, then, bead 14 in the rail section of rear end is one by one stirred successively to the front end rail section that slides onto guide rail 1, straight only dial the number of the bead 14 that moves to front end rail section when identical with the digital value of light-emitting diode display 3 settings till, can complete once " putting number " teaching and training.Finally, allow child that digital value is set voluntarily and dial and to move bead and repeatedly carry out repeatedly " putting number " exercise.In fact, this " putting number " teaching is a kind of reverse thinking training method of " knowledge counting number " teaching just, it from different perspectives guiding student further know from experience the relation between number in kind and abstract numeral, can firmly set up the relevance between abstract numeral and corresponding material object, in arithmetic education training, have splendid teaching efficiency.
Obviously; above-described embodiment is only to realize one of mode of technical solutions of the utility model; the claimed scope of the utility model is not limited only to above-described embodiment, also should comprise the alternate manner that can be changed according to the technical solution of the utility model by those of ordinary skill in the art.
